Hi!!! I used to have a bunch on obsessive, intrusive thoughts. I would stay up all night just worrying and obsessing. I dont remember what the remedy was but I rememeber how bad it was.

Intrusive thoughts is a lot of what my Ocd is. They can be really small or really scary & disturbing. I am on medication which helps of course. A short term remedy is distraction, keeping yourself busy. If you have triggers you can stay away from them but that is also rather short term. Your therapist should help a lot, just make sure to tell them everything, be open with them no matter how dark or scary your thoughts may seem.
